The town of Ocean Hills is located on a map at the point (9, -8). Sandy Shores is located on the same map at the point
(1, 7). What is the approximate distance between the towns if
each unit represents 10 miles?

1 and 2

step-by-step explanation:

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
